DOUGH-'DIVI'DER.

Specification of Letters Batent.

Patented July 3,1906.

Application filed July 27, 1905. Serial No. 271,431,

To all whom it may concern.-

Be it known that I, FRANK STREIOH, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Dough-Dividers, of which the following is a specification.

This invention relates to improvements in machines for dividing masses of dough into lumps suitable for forming loaves of bread and the like.

The especial object of the improvements described in this application is to produce a machine of the simplest mechanical construction that will accurately and effectively divide the dough without impairment of the material and that will handle the material with minimum contact with the mechanism of the machine.

In the accompanying drawings, which forma part of this application, Figure 1 is a side elevation of my dough-divider inan approved form. Fig. 2 is an end elevation of the same. Fig. 3 is a detail in vertical section, showing the hopper .and parts contiguous thereto. Fig. 4 is a side elevation of the machine, taken from the side opposite to that shown in Fig. 1 and on a larger scale.

Referring to the details of the drawings, 1 represents the main frame of my improved machine, which is provided with braces 1, horizontal extension 1 and a vertical extension 1.

2 represents a hopper, which is bolted to the extension 1 and is open at the top and bottom.

4 is a shaft suitably journaled at the outer end of the extension 1, on which is fixed a roller 4*, and on the outer end of the shaft 4 is mounted a pulley 4, over which travels an endless belt 4. A similar shaft and a roller 4 are mounted at the opposite end of the machine in a bearing block adjustably mounted in the bracket 4 in the usual manner. An endless apron 3 is arranged over the said rollers and forms the table of the machine.

5 is a shaft suitably journaled in the frame 1, and on the outer end of the shaft are mounted tight and loose pulleys 5 5*, respectively. A small belt-wheel 5 is secured on the shaft 5 outside of the frame and near the pulley 5, and the belt 4 is arranged over said wheel, as shown in Fig. 2. A pinion 5 end is pivotally the rack-bar .9, the teeth 9 of which are formed .on the opposite edges of the bar, as

is mounted on the shaft .5 and meshes with and drives-the gear-wheel 6, which is mounted near .one end of the shaft 6, said shaft being suitably journaled in the frame and car ry-ing at its end adjacent to the gear 6 an arm 6, in whicha pin 6 is secured. Mounted on oneend of the shaft 6 is anarmfi vcarrying a block that is adjustable in said .arm by the bolt 6 Projecting from the block is a pin :6, on which is pivoted the lower end of a rod 7, the upper end of which is similarly oonnectedwitha pin7,-which projects-from a block mounted in the arm 7 which is provided with the adjusting-bolt 7. is pivotally mounted on the shaft 11, which is suitably journaled the extension 1 of the main frame of the machine. Said shaft 11 has secured thereon a cut-off 11, formed with a curvedfacaas shown in Fig. 3.

8 representsa lrodthe lowerend of which is loosely mounted -on the .pin '6, and .the upper connected by a pin 8 with SllOW-Xhill Figs. 1 and 2. The plain portion of the rack-bar is slidably mounted between the guide-rollers 8 which are mounted onpins projecting from the side of the frame, as shown in Fig. 1.

10 1O representshafts which are journaled in the extension 1 and have mounted at one end segmental gears 10*, the teeth of which mesh with the teeth 9.of the rack-bar. On said shafts are also fixed the dough-feeding elements 10 10", which are formed with curved faces 10 10 and the squared face 10 and are so mounted as to form oscillating gates for the lower end of the hopper 2, as clearly shown in Fig. 3. Secured between the frame extensions 1 is a dough-receiving box 12, which is open at the top and bottom and has its upper edges squared to abut against the squared portions 10 of the elements 10 and its lower edges curved to fit the curved face of the cut-off 11. The faces 10 10 of the elements 10 are formed at different radii, so that when the faces 10 are in the position shown in Fig. 3 they practically close the lower end of the hopper; but when said elements have been oscillated on the shaft 10'to the position shown in Fig. 4 they will permit the dough to feed down into the box 12.

The operation of a machine constructed Said arm substantially as described will be as follows: Power being applied to the pulley 5 the shaft 5 will be driven and in turn will rotate the belt-wheel 5 and the pinion 5 Through the belt 4 the wheel 5 will drive the pulley 4 and thus through the rollers 4 4 drive the apron 3 The pinion 5 will drive the gearwheel 6 and the shaft 6, on which it is mounted, and will thus rotate the arm 6? and drive the rod 7, and through said rod the arm 7 will be oscillated and cause like movement in the shaft 11 and cutoff 11*. The shaft 6 will also rotate the arm 6, and thus drive the rod 8, which in turn will reciprocate the rackbar in a vertical plane, and thus through the segments 10* oscillate the elements 10.

certain amount of the material will be forced downwardly by the squared faces 10 of the elements 10 into the boX or receptacle 12. The stroke of the elements 1O regulates the amount of dough fed down into the box, and this stroke is adjustably controlled through the position of the segmental gears on their respective shafts relative to the position of the said elements on the same shafts. The dough by reason of its nature will remain in the boX 12 until forced out, and this is done by the next following lump of dough in connecti on with the cut-off, which severs the first lump and permits gravity to act. The lumps first formed will not be accurately scaled but after a few operations and the proper adjustment of the connections of the rod 7 the amount of dough entering the boX 12 at each downward movement of the shoulders 10 will be uniform.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. In a dough-divider, a supporting-frame and a hopper secured thereon, a dough-receptacle arranged below said hopper, oscillating dough-feeding elements mounted in the lower As-v suming that the hopper is filled with dough, av

portion of the hopper, said elements having faces adapted to force a portion of the dough into said receptacle, means for operating said dough-feeding elements, and a cut-off for the dough.

2. In a dough-divider, a supporting-frame and a hopper secured thereon, oscillating dough-feeding elements mounted in the lower portion of the hopper, said elements adapted to force a portion of the dough downwardly, a dough-receptacle arranged below the hopper and adapted to receive the dough therefrom, means for operating said doughforcing elements, an oscillating cut-ofl arranged below said receptacle, and means for operating said cut-off.

3. In a dough-divider, a supporting-frame,

and a hopper secured thereto, oscillating dough-feeding elements mounted in the lower portion of the hopper, said elements adapted to force a portion of the dough downwardly, and to form a closure against the rest of the dough in the hopper, a receptacle adapted to receive the dough from the hopper, means for operating said dough-forcing elements, an oscillating cut-off arranged below said receptacle and means for operating said cut-off. V

4. In a dough-divider, a supporting-frame and a hopper secured thereto, oscillating dough-feeding elements 10 mounted in the lower portion of the hopper, a receptacle arranged below said elements and adapted to receive portions of the dough from the hopper, the cut-off 11", means for operating the dough-feeding elements and means for operating the cut-off.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANK STREIOH.
